Original bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111731 Given that this is a regression, is this okay for gcc 13 and mainline? The unwinding mechanism registers both the code range and the unwind table itself within a b-tree lookup structure. That data structure assumes that is consists of non-overlappping intervals. This becomes a problem if the unwinding table is embedded within the code itself, as now the intervals do overlap. To fix this problem we now keep the unwind tables in a separate b-tree, which prevents the overlap. libgcc/ChangeLog: PR libgcc/111731 * unwind-dw2-fde.c: Split unwind ranges if they contain the unwind table.
I'll go ahead and give the final OK here :-) Jeff
